Which type of explosive is classified as a firework?

The correct answer is pyrotechnics, as this category encompasses materials primarily designed for visual and auditory effects, such as fireworks. Pyrotechnics include a range of devices, from simple sparklers to complex aerial shells, which are intended for entertainment and celebration purposes. These materials are characterized by their ability to produce effects through rapid combustion, which is distinct from the characteristics associated with low order and high order explosives.

Low order explosives, like smokeless powder, typically burn at a slower rate and are often used in ammunition, while high order explosives, such as TNT or dynamite, detonate and produce a shock wave. Blasting agents are usually stable substances that require a booster or detonator to explode and are primarily used for industrial purposes, such as mining or demolition. In contrast, pyrotechnics are specifically created for performance and enjoyment, making them the fitting classification for fireworks.
